Hi Chris. You may remember me, I was on staff when we banned you. From what I've seen, it looks like you're okay to come back so long as you're well behaved going forward.
I will merge your accounts, leaving you with your old account open for use. If you don't have the password for your old account, let me or another admin know (I'm sure you'll find a way!) and we should be able to help you out.
EDIT: Well, I will merge your accounts once our account merging feature decides to not give me a technical fault. =P
